TREEING-IRON.

Application filed January 17, 1917.

To all whom it may concern Be it known that I, TILLIAM I. THOMP- sox, a citizen of the United States, residing at Stoneham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Treeing-Irons, of which the following is a specification. I

This invention relates to treeing tools, or irons so called, such irons being usually electrically heated and adapted to act on portions of a lasted shoe upper, and it is embodied in an iron of improved form whereby the range of work for which the iron is adapted is considerably increased.

Of the accompanying drawings forming a part of this specifieation,

Figure 1 represents a side view of a treeing tool embodying the invention.

Fig. 2 represents an end view of the tool body or iron.

Fig. 3 represents a section on line 33 of Fig. 1.

Fig. 4E represents a section on line 4.l= of Fig. 1.

Figs. 5. 6, 7 and 8 represent different portions of a shoe and illustrate different uses of the tool.

Fig. 9 represents a conventional application of electrical heating means to the tool.

The same reference characters indicate the same or similar parts in all the figures.

a represents an elongated metal body which is approximately wedge-shaped in cross section. and has a relatively wide, sub stantially flat elongated base face 12. and an acute angled elongated apex 13. The sides of the body converge from the base toward the apex thereof. and include concave side faces 1% and narrow elongated longitudinal faces 15 joining the side faces 14 to form obtuse angles 16. said faces converging and joining each other to form the apex 13. The end faces 17 of the body are curved inwardly from points near the apex 13, to form tapering horns the sides of which are formed by the end portions of the narrow elongated faces 15. the apex 13 extending to the outer ends of said horns.

The end faces 17 have lateral curved ex- Specification of Letters Patent.

tensions 17 joining the concave faces 14-, as indicated by Fig. 4.

The general form of the body or iron (0 is such that it is adapted. to meet all the requirements of a treeing iron.

The chief novelty of the invention resides in the concave faces 1%. the narrow elongated side faces 15 forming an acute angled apex 13, and the horns having their sides formed by extensions of the faces 15 and apex 13.

The concave faces 16! are adapted to act on convex portions of a shoe upper, as indicated by Fig. The acute angled apex 13 is adapted to act on a narrow shoulder such as the edge of toe cap. as shown by Fig. 6. The horns are adapted to act on portions of an upper of limited area such as the portions of a button shoe surrounding the buttons thereof. as indicated by Figs. 7 and 8. The body a has a socket Z) adapted to receive an electrical heating unit. and is provided with handles, 0, c.

Said heating unit is shown conventionally by Fig. 9. in which (Z designates the resistance wire. and c, c the circuit wires extending through one of the handles 0. Said handle may be detachably secured to the body a by any suitable means. so that the heating unit may be inserted in and removed from the socket 7), said unit being provided with a cylindrical casing fitting said socket.

I claim 1. A treeing iron approximately wedgeshaped in cross section and having a relatively wide elongated base. an elongated acute angled apex. concave side faces which converge toward said apex and are adapted to act on convex port-ions of a shoe upper. and narrow elongated longitudinal faces joining said concave side faces and meeting each other at an acute angle to form said acute angled apex. which is adapted to act on a. narrow shoulder on a shoe upper.

2. A treeing iron approximately wedgeshaped in cross section and having a relatively wide elongated base. an elongated acute angled apex. concave side faces which converge toward said apex and are adapted to act on convex portions of a shoe upper, near said apex to form horns adapted to narrow elongated longitudinal faces joinact on limited areas of the upper, the end ing said concave side faces and meeting each portions of said narrow elongated longitu- 10 other at an acute angle to form said acute dinal faces forming the sides of said horns.

5 angled apex, which is adapted to act 011 a In testimony whereof I have atfixed my narrow shoulder on a shoe upper, and end signature.

faces Which are curved inwardly from points l/VILLIAM I. THOMPSON.
